Question

Two Numbers are such that the ratio between them is three is to 5 if each is increased by 10 the ratio between the number so formed 5 to 7 find original number

Answer 1

Step-by-step explanation:

Let the no.s be 5X and 3X.

INCREASED BY 10

Result = 5:7

3X + 10/ 5X + 10 = 5/7

7(3X + 10) = 5(5X + 10)

21X + 70 = 25X + 50

70 - 50 = 25X - 21X

20 = 4X

20/4 = X

5 = X

ORIGINAL NO.

5X = 5*5 = 25.

3X = 3*5 = 15.
